Self-propelled movement of an organism from one location to another through water, often by means of active fin movement. [GOC:cvs, PMID:22459995]

Swimming is a complex biological process that involves coordinated movements of the body and appendages to propel an organism through water. The process involves a combination of muscular force, buoyancy, and hydrodynamic principles.

Firstly, muscles contract and relax in a synchronized pattern, generating force against the water. This force can be generated by the body's limbs, fins, or even the entire body, depending on the organism's morphology. In fish, for example, powerful tail muscles propel them forward. In humans, swimming strokes involve the coordinated movement of arms and legs.

Secondly, buoyancy plays a crucial role in swimming. Water exerts an upward force on any object submerged in it, opposing the force of gravity. This buoyancy allows organisms to float and reduces the effort required for movement.

Thirdly, hydrodynamic principles govern how water interacts with the organism's body. Organisms with streamlined shapes experience less resistance from the water, allowing them to move more efficiently. The shape of fins and other appendages also contributes to the efficiency of swimming.

The specific mechanisms of swimming vary greatly among different species. For example, fish use their fins and tails to propel themselves through the water, while whales use their flippers and tail flukes. Birds use their wings to generate lift and thrust, allowing them to swim on the surface of the water.

Ultimately, swimming is a highly efficient and adaptable form of locomotion that allows organisms to move through aquatic environments. It involves a complex interplay of muscular force, buoyancy, and hydrodynamic principles.'
